    Default Percentiles for premies

    When calculating a premie's percentiles for weight, do you just go off adjusted age? I remember that the NICU had a chart based on gestational age at birth to calculate his % before he reached 40 weeks.

    We have always done (and the doctors) the adjusted age.....

    Unhappy Re: Percentiles for premies

    I just took DS to the ped yesterday, and they have all their charts computerized. I was bummed that their software wasn't able to account for the fact that DS was born at 35 weeks, and his corrected age is 1 month.

    Mine was born at 30 weeks and his ped just started using the computerized records too. It puts his weight at below the 3rd. But, our ped still pulls out a paper chart just so we can have a peek at his true percentiles. Even on the computer, what they really look for on the chart is not so much where your LO lands, but whether he/she consistently lands in the same area. In other words, that there's not a huge spike in weight gain or loss. My boy is small, but consistently small. The ped is much more interested in whether he's meeting his milestones (also based on adjusted age, btw). The neonatal specialists that took care of DS do followups with him too, and they always adjust his age. By that reckoning he's still small but definitely within normal ranges.

    Most doctors that have experience with premature infants do adjust for age. On top of that, there are some charts available specifically for preterm infants.

    You can find one here:

    Here's a good set of links for image files of the chart:

    As others have said though, the docs are mostly looking for the baby to keep growing at a RATE appropriate for its gestational age.

    Remember too, being small isn't a health problem in itself. Doctors sometimes get a bit worked up about size because being small is CORRELATED to many health problems, but it's often those underlying health issues that cause the smallness, not the other way around. It's perfectly fine to be small and healthy.

    My daughter born at ~34 weeks (her due date was last weekend) on each of her measurements has been just at or below the 3rd percentile for weight, just below the 10th for length, and what looks to be ~30th for head circumference. And she's pretty sizable compared to her full term 4.5yo brother who has spent his entire life below the 3rd percentiles for height and weight (with head circumference ~50th), but is in all respects very healthy intelligent strong and vigorous. He's not much of a drawer, but builds wonderfully complex lego structures.

    Thanks for the replies and links!

    My LO had his 2 mo appt with his pedi and without correcting his age he was in the 20th percentile for both height and weight! When he first came home from the special care nursery he was well below the charts. Hooray for booby milk!
